Here’s my ‘quick look’ at the Six Vedanga: they formed an ancient language science (from which modern Indo-European languages and rules evolved).

Vedanga (n., pl.|Sanskrit: वेदाङ्ग vedāṅga, “limbs of the Veda”).

The Six Vedanga are rooted in very-deep antiquity. The Brihadaranyaka Upanishad mentions them as integral parts of the Brahmanas layer of the Veda.[19] We can trace each of these study fields to the 2nd millennium B.C.

Fifth-century B.C. scholar Yaska quotes the Vedanga. However, it is unclear when and where the full six-Vedanga list was first conceived and compiled.[20]

The Vedanga likely stem from a time in or after the middle of the 1st millennium B.C. These “auxiliary Vedic fields” arose when the Vedic-text language composed centuries prior had become too archaic to people in a later era.[21]

The Vedanga were sciences focused on understanding and interpreting Vedas composed many centuries prior.

The Six Vedanga developed as Vedic “ancillary studies” or insights into poetic meters, sounds and language structures, grammar, linguistics and other post-Vedic studies, arts, culture and various schools of Hindu philosophy.[22][23][24]

As such they were the core curriculum of early Indian drama & literature schools.

Kalpa Vedanga gave rise to Dharma-sutras that later morphed into Dharma-shastras.[21][25]

Nirukta pertains to linguistics for setting precise meanings of words (given their contexts).[13]

5. Kalpa (kalpa): ritual instructions.[13]

Kalpa is about official and/or the standard procedures in Vedic and rites of passage rituals (assoc. w/major life events like births, weddings and deaths, as well as moral conduct and societal expectations on individuals in different life stages).[14]

The character of Vedangas has roots in ancient times, and the Brihadaranyaka Upanishad mentions it to be integral parts of the Brahmanas layer of the Vedic texts.[19]

Individually, these auxiliary disciplines of study are traceable to the 2nd millennium BCE, and the 5th-century BCE scholar Yaska quotes the Vedangas. However, it is unclear when and where a list of six Vedangas were first conceptualized.[20]

The Vedangas were sciences that focused on helping understand and interpret the Vedas that had been composed many centuries earlier.[21]

Vedangas developed as ancillary studies for the Vedas, but its insights into meters, structure of sound and language, grammar, linguistic analysis and other subjects influenced post-Vedic studies, arts, culture and various schools of Hindu philosophy.[22][23][24]

The Kalpa Vedanga studies, for example, gave rise to the Dharma-sutras, which later expanded into Dharma-shastras.[21][25]
